SO2 SO3 emissions
(OP)
Hi Folks
what is the generally accepted emission removal process for Offgas mainly containing SO2 and SO3
Any reference or literature you could recommend?
many thks

Depending on design, efficiencies greater than 99% can be achieved, though high efficiency is easier with NaOH (expensive) than lime (cheap).
Look up flue-gas desulfurization processes as a starter. There is a large amount of existing literature on this.
Oh, and when scrubbing SO2, you’ll need to further oxidize the resulting sulfite ion to sulfate to prevent chemical oxygen demand as well as potential re-release of SO2 if solution pH drops.

Consider the resource attached .
Note : you should consult your local EPA for the limits in your area.
